Thanks for choosing health care magic for posting your query.
From the description that you have given it appears that you are probably having depression
You should consult your psychiatrist
who would like to evaluate in detail and probably start you on some antidepressants. he may also like to conduct a few Cognitive behavioral therapy
sessions for you.
Meanwhile you can start doing regular exercise and also engage yourself in some hobbies.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
